@didgesteve I emailed them on Mon still waiting for a reply. I did mention that products are great, and that it’s a shame the lack of communication is the only thing that lets them down. Shame really 😞
If your antenna + according circuit is matched at 13.56Mhz, there are no problem but I think it will be difficult to find an antenna that match with the according circuit currently on the keyduino and you will need to change some component value to improve your reading range ;)
Here's my reply from support at the end of Febuary
"We're in the final stages of refining production of the payment-enabled NFC Ring (and associated back end systems) at the moment. We're currently aiming to begin dispatch in the next couple of months."
@flux_capacitor - We have this scheduled for further investigation and development, so will be able to update on the possibilities with the NFC Ring as soon as that happens! We have iOS11 dev version to test with, so will report back on this asap.
I think you need to go back to the safe manufacturer to find out which chip it supports. You might even find it on the spec sheet of the product.
You need a sensor that will work with NTAG. In theory if it works with NTAG and is programable IE: accepts a scanned chip, then it should work. Perhaps find a shop that sell them and turn up with your ring, see if it reads it and can be programed to accept it.
There are lots of sensors and locks that are designed to work with MIFARE chips, which won't work with the NFC ring.
So just read up before you make a purchase.
Hi, I understand MIFARE cylinders and NTAG chips used in NFC rings share the same NFC frequency (13.56 MHz) and the same ISO/IEC 14443 standard. I don't understand the limitation, especially as NFC ring say in their FAQ:
"All door locks with NFC (ISO14443) should work fine."
So maybe the cylinder you bought is not ISO-14443 compliant?
Looks like your connection to NFC Ring Forum was lost, please wait while we try to reconnect.
